Reference is a central issue for language comprehension and generation. After reviewing existing process models for comprehending and generating referring expressions, we present a general framework for context and reference processing. The context for reference processing is represented as a Public Workspace. Reference processes access Public Workspace and modify its content, which is the set of concepts currently on the table as far as the current language interaction is concerned. Information from many different sources can be integrated in comprehending or generating referring expressions. Within this general framework, a new system for selectively generating referring phrases is developed. This system decides how much to express about a given concept in a given context.
